Years of development, testing and fine tuning has made our Prusik cord a preferred choice by rescue schools, agencies and rescuers alike. Our Sewn-Loop Prusiks offer unmatched performance—with strength equivalent to a tied Prusik loop, just without the cumbersome knot. The factory-sewn SecureStitchTM is covered with durable clear shrink tubing that allows regular inspection and helps protect the stitching for longer life. These loops are produced with our 8mm Prusik cord.
